The Instagram (Facebook) Hashtag Search API has an imposed limit of 30 hashtag searches in a rolling 7-day window, per Instagram Business Account. Instagram counts the number of unique hashtags that are searched rather than the number of requests, so you can search the same hashtag multiple times which will count as 'one hashtag' in terms of this limit.
While the limit is sufficient for most marketing use-cases, attempting to activate or preview an Instagram hashtag feed once this limit has been reached will fail. You will be warned when you are approaching the limit and alerted when further searches cannot be performed. When the limit is reached, existing feeds will continue to execute but you will not be able to preview or activate further feeds until such time as there are less than 30 hashtag searches over the last 7-day period.
Please note that any other systems searching for hashtags using Hashtag Search API will also count towards this limit.

What do do
There are two courses of action available when this occurs:
- Wait and try to activate the feed at a later time/date
- Use a different Instagram Business Account
Using another Instagram Business Account
At present, you may only connect one Instagram Business Account to a Fanpage, this means that in order to use another Instagram Business Account to activate a feed or preview results, your Facebook user account must have a role on another page with a different Instagram Business Account connected. As shown here:
The steps outlined in this article will explain the full process of creating a new Fanpage (if another is not available for your use) and connecting it to an another or new Instagram Business Account.
When more than one Instagram Business Account is available to use, you will be able to select another account from the drop-down list in your feed.
We recommend searching and exploring Instagram hashtags using the Instagram app or website and, once the relevant one has been identified, setting up your feed in the platform. This will avoid exploratory searches counting towards your 7-day limit.
